Product details

800V breakdown — headroom for universal input and surge

The 800V drain-source breakdown voltage on the integrated MOSFET provides primary-side switch margin for universal AC input plus reflected voltage and leakage-inductance spikes. A 50% duty cycle limits primary on-time.

77 W at 52 kHz — sizing the transformer and bulk cap

The 77 W power rating defines output capability for a continuous-load flyback. At 52 kHz, the transformer core volume and turns ratio are sized for this power level.

Protection set and thermal range

Built-in fault protection covers current limiting, overload, over-temperature, and over-voltage for adapter-type supplies without an external supervisor. Junction temperature range is -40°C to 150°C.

Frequently asked questions

Does ICE2QR1080GXUMA1 have an integrated MOSFET?

Yes. The ICE2QR1080GXUMA1 integrates an 800V CoolMOS power MOSFET and a quasi-resonant flyback controller in one package. No external MOSFET is required for the primary switch.

What is the pinout of ICE2QR1080GXUMA1?

The ICE2QR1080GXUMA1 is supplied in a 16-SOIC package with 12 functional leads (PG-DSO-12-19). The pinout is standard for the CoolSET-Q1 family; the datasheet provides the full pin assignment including drain, Vcc, FB, and CS.

What is an equivalent or cross reference for ICE2QR1080GXUMA1?

Within the same CoolSET-Q1 series, the ICE2QR2280G1XUMA1 is a lower-power sibling (53 W vs 77 W) but shares the same 800V breakdown, 50% duty cycle, and fault protection set. For a higher-frequency alternative, the ICE3AR1080VJZXKLA1 (100 kHz, 71 W, through-hole) is a different package and topology variant.
